After years of continuous use, they have provided all the functionality as advertised. I’ve thrown all types of your typical electrical devices at these, sometimes with USB chargers of varying lengths connected simultaneously. I’ve experienced no failures or concerns. I tend to leave the USB charging functionality on at all times, even if there nothing connected. The item can get slightly warm when it is being utilized to the fullest, but not enough to warrant any concern.
I would not throw something requiring an extreme amount of wattage at these, such as a hair dryer or space heater, but that is typical of all power extenders. Also, for expensive and critical electrical devices, you would want to purchase an extender with a high degree of surge protection. However, for everyday practical purposes, these perform admirably.
*Disclaimer - I have received no compensation for this review. This review is of my own volition.
I am able to connect 3 usb connections to it and it is the fastest way for me to charge my phone.
I have tried direct connections into my regular home outlets and this extension cord is still able to charge faster due to its smart charging.
It sits at the edge of my couch and I use it to connect everything!
It has 3 connection sides and 3 usb slots.

Comes with 3 outlets and 3 USB A ports. With this power cube I can recharge my laptop, use two charge bricks to fast charge my work and personal iPhones at 18W each, and use the 3 USB ports to connect my headphones, watch and power bank battery. Perfect for those times when you are on the road and need to set up a workspace like in an airport on a layover, board room for a marathon meeting or hotel room at the end of the day.
Comes with a sticker so you can mount it on the underside of a desk, I stuck it to a magnet so I can stick it to a wall to keep it up and out of the way.

Here you have a compact cube on a 5ft odd wire (3 power ports) with some surge protection…… and (I wll test it tonight) with one small blue light which emits light IF you wish to use the USB ports (3 of them) overnight. A small round power button at those ports will nullify that “light pollution” (and power to the USB ports) if you so wish.
I would say it’s a 75% improvement on the bulky, heavy light emitting power extenders we used before this, bedside.
If you like minimalistic light products for a better night’s rest, these should work 👍. However, Inam also adding a “light dim sticker” on the button (which will remain functional) as to make it a zero light emission power hub.

It doesn't have an on/off switch for the main power which some people might find inconvenient if you aren't using it for travel. Mine is installed permanently because I just wanted the small form factor compared to my other power strip. I just plugged it into a TP-Link smart plug and now my Google Home turns it off and on as needed. Really pleased with this so far, but I can't comment on long term use yet, since I just got it today.
